Description :
In this study Cs 137 and Pb 210 were used to determine surface and sub-surface source contributions of fine sediment in a small upland headwater catchment in the Central Tablelands region of New South Wales. The findings from this analysis are employed in an adjustment procedure to better differentiate sediment source erosion processes by utilising channel survey and erosion pin data. Variability in sediment source contributions within the catchment was high, with rapid transition from hillslope to channel source dominance of sediment flux with distance downstream in the study catchment.
